I'm developing a custom language support plugin for IntelliJ following the IntelliJ tutorial (not strictly because I'm adapting it to my language, but as strictly as possible). Now I'm trying to write some tests but I can't even do a little POC because when I try to run the tests I see a message saying: "Tests events were not received". For developing my tests I'm following the IntelliJ guide as well, and my test class is BloblangParsingTest.

My code is visible on GitHub in the branch add-tests. I also added a github action to run the tests and I'm getting the same result (the message mentioned above seems to be given by IntelliJ, but the console outputs are the same).
